Struct DenseBitmapScheduler

pub struct DenseBitmapScheduler { /* private fields */ }

A physical scheduler for bitmap buffers encoded densely as 1 bit per value with bit-endianness(e.g. what Arrow uses for validity bitmaps and boolean arrays)

This decoder decodes from one buffer of disk data into one buffer of memory data
